Fiserv finds itself at the centre of a political and financial storm as former CEO Frank Bisignano faces Senate scrutiny.
US Senators Elizabeth Warren and Ron Wyden have requested information from Fiserv regarding the company’s operations under former CEO Frank Bisignano.
The Senate Democrats have cited concerns over his ability to serve in senior government roles.
Bisignano currently leads the Social Security Administration (SSA) and was recently appointed CEO of the Internal Revenue Service under the Donald Trump Administration.
On November 7, the senators wrote Bisignano “appears to have failed to manage Fiserv effectively, and may have misled investors and the public about the company’s financial status, raising concerns about his ability to serve as a key Social Security and IRS official in the Trump Administration.”
The pair added that as a result of mismanagement: “many Fiserv investors, including retirees and members of the public, lost money – a fate Mr. Bisignano avoided.”
The scrutiny follows an earnings call last month, where Fiserv reported third-quarter revenue up just 1% year-over-year and adjusted EPS down 11%, sending shares down more than 40% in a single session.
Management described the results as a “reset to a new financial baseline,” citing margin pressure, weak performance in its Financial Solutions segment,and a guidance cut which lowered full-year organic growth expectations from roughly 10% to 3.5-4%.
Controversies at Fiserv
Concerns over Bisignano’s tenure at Fiserv come amid ongoing operational issues, with a class-action lawsuit claiming the company overstated growth in its Clover point-of-sale platform.
Thousands of small-business customers were moved from the older Payeezy platform to Clover without fully disclosing the risks. Internal data showed early signs of dissatisfaction, but this was not shared with investors, creating the appearance of stronger, more sustainable growth.
Executives, including Bisignano, told investors revenue growth came mainly from new merchants, while back-book conversions played a minor role. In reality, Payeezy customers were increasingly leaving the platform.
Then shortly before assuming his government role, Bisignano divested over $550m in Fiserv stock, just months prior to a share price decline of more than 44% following a reset of the company’s financial outlook under new leadership
Government role under question
The situation intensified in September 2025 when a Fiserv subsidiary was awarded a Treasury Department contract to manage debit card distribution for Social Security and other federal benefits, serving more than 3.4 million Americans.
Notably, this contract was not disclosed during Bisignano’s confirmation process to lead the SSA.
Senators Warren and Wyden are now demanding transparency around the contract award, including details on internal investigations, federal negotiations and any non-disclosure agreements signed by Bisignano.
The lawmakers have been critical of Bisignano’s appointment from the beginning. In March 2025, they raised concerns about potential conflicts of interest between Fiserv and federal programmes.
In July, Senator Warren had secured a series of commitments from him on matters including Social Security data, staffing levels and payment operations. Then in October, the senators pushed back against the Trump administration’s decision to place him in a second powerful role, this time as CEO of the IRS, while still serving as SSA Commissioner.
